Many years ago I bought a brand new Glenfield 60 & (Weaver?) scope combo from the local K-Mart for a whopping $69.95 that was made well before they came out with the bolt hold-open. It was an absolute tack-driver and never had a single failure of any kind. Several years later I sold/traded the gun for something else (can't remember what...) and eventually started missing having it around.
I thought - No problem, I'll just buy another one. So off to the store I went to pick up another model 60. This gun had the bolt hold open, and sold for $99.00 without a scope. I added a Tasco 3-7x20 wide angle scope and headed for the range. This time I encountered a few jambs. A couple failure to feed at times, and although it shoots decent groups it isn't near as accurate as my old rifle was.
Not to say this will be true in every case, but I have heard others say the same thing before. The only thing Glenfield designates is that it is Marlin's "economy" line of rifles.
